The interface resistances of magnetic multilayers are calculated witho
ut an adjustable parameters by combining first-principles electronic s
tructure calculations with the Boltzmann equation. The microscopic mec
hanism of specular interface scattering in combination with diffuse bu
lk scattering can largely explain the experimentally observed values f
or the interface resistances of Co/Cu multilayers. (C) 1998 Elsevier S
